Abstract: The invention is related to a plant for the classification of scrap according to its chemical composition. The plant contains a shear adapted to cut scrap; downstream of the shear an analyser of the chemical composition of the sheared material; means of transport, comprising a plurality of vibrating feeders and conveyors to transport the sheared material to the analyser; and a discharge system adapted to divide the material analysed according to its chemical composition. The shearing in a related method is followed by chemical analysis of the sheared material which allows its division into fractions of sheared scrap with different chemical compositions. The invention helps to optimise the feeding of melting furnaces with different types of scrap which are distinguished, for example, by their copper content.

Abstract: An electromagnetic device for laterally containing a liquid metal, having a first electrical conductivity, at one open side end of a passage defined between two counter-rotating casting rolls, at least the surfaces of which are made of a ferromagnetic material, said device comprising a magnetic yoke made of a further ferromagnetic material having a second electrical conductivity either lower than or equal to said first electrical conductivity of the liquid metal and ending with two mutually proximal wedge-shaped ends, said wedge-shaped ends having respective inner surfaces, facing each other and defining a gap, and respective outer surfaces, arranged one on one side and the other on the other side with respect to a plane lying in said gap and shaped so as to be able to insert both said wedge-shaped ends at least partially between the two casting rolls; at least one coil wound on at least one stretch of the magnetic yoke and adapted to be supplied by electric current; at least one plate, made of a material

Abstract: A method for electromagnetic stirring of liquid metal in a continuous charge electric arc furnace, in which there are positioned a first electromagnetic field along a first axis of electromagnetic stirring and a second electromagnetic field along a second axis of electromagnetic stirring.

Abstract: A heating device and/or method to heat a slab, and in particular its edges, by electromagnetic induction, including an electric coil and a magnetic concentrator associated with the electric coil.
